Application yfiled .ecember Myinvention relates to a new vand usetul improvement in a detachable'anti-skid tread adapted for mounting onlvehicle tires and the lilre to provide,A means for gripping the surface over which the tireis 1riven and to prevent a lateral slipping of the tire on the surface. Y

The object oic the present invention is to provide an anti-skid tread of this cla-ss which may be easily and quickly attached to a vehicle Wheel bearinga tire.

Another object of the invention is the provision oi an anti-slrid tread of this class which may be so mounted upon the Wheel as to prevent creeping` of the saine about the tire on vwhich mounted. Y

Another object of the in Viention is the provision of an anti-skid tread oit this class having detachable gripping members so that they may be removed and replaced When ivorn thus lendingalong lite to the device.

@ther objects will appear hereinafter.

The invention consists in the combination and arrangement of parte lereinaiter Adefntion will be best 'understood renee to the accompanying dra\v ga, which vforni a part of this specilication and in whichj j Fie'. 1 isa side elevational vievv of a Wheel g the invention applied. 1 2 is a sectional View taken on substantially line 2 2 of Fig. 1. l 3 is a ii'ao'mentary perspective view of the tread portion.

f a .shown in the drawings, the invention is for use Twith a vehicle Wheel having a tire 7 mounted upon the ueual'rini VE) which positioned about the 'telly 8. 1 Y

fis shown in ig. 2 the rim engaginglugs 10 areeecnred tothe telly by thel bolt 11 upon which threaded thenut .12. The dc taehable tread in which the invention consistsfconiprises a pair of trough-shaped sections 13 and 142 which are positioned about the periphery of the tire7 so as to form Ya )or the tread portion thereof. it is 1 that as many of these Section5v 13 el may be used as desired in order to eX- tend around the periphery ofthe tire although. as shown in the drawings l prefer to construct the device troni tivo sectionf-. EX'- tending longitudinally over each section 13 and 111 centrally thereof and secured thereto in any suitable manner such as by Welding 7, i925. seriaiufno. 73,644.

or the, like are reinforcing bars 15. Formed on ythe members v13 and 14 at spaced intervals are lugs pivotally connected to Which are retaining lclips '16 and 17. The cliplol is angularly turned at V16 to lie in engagement with the. inner gsurface of the 'elly. This angulaily turned portion being,` again angularly turned to provide the 'inwardly extending portion 1G. The end of the member 17 is also angularlyturned as at 18 andlQ-the angularly turned portion being again angularly turned to provide the inwardly projecting portion 20, so that the inner surface ot the elly is embraced by the end of the clip 17. A suitable bolt 21" is projected through the inwardly projecting angularly turned portion 16 and 2O to bind the device upon the telly. n

The member 17 is provided with an opening 17 yforthe 'reception Vof the bolt 11 so that Ythe deviceV is prevented from creeping I about the tire When in use, f l. l @ripping members are provided each hav= ing a threaded stem 22 which is threaded in- 'to the rei'norcingv bar 1'5 a id the eectiona 13.

and 1&1. Each of these stems 22 is provided with. a pointed head 23 to form a gripping member for gripping the surface over Which. the Wheel is passed. 1t is evident that these gripping members are detachable and that they may bel removed and replaced when Worn. It is also .evidentthat they Will on account of being projected beyond the outer f surface of the reinforcing bars 15 be the only parts of the device which are directly sub jected to vicar on account of contactivith thel surface over which the Wheel may be paesing, sothat by renewal of the grippng meinbers 23 the lite of the Vdevice may be prolonged., considerably. Projecting outwardly troni opposite sides of the sections 13 and 14C areflaps 24 and 25 Which serve to engage a larger Vportion of the tire 7 than does the main body 'of the sections 13 and 14l-.-tliese flaps Vserving a larger bearing surface and assuring' amore snug engagement of the Clevice With the periphery of the tire.

1t is believed obvious that in mounting the'V device it is positioned about the tire and the bolts 21 project through the'v portions 2O and i6.- i n.

While l have illustrated and described the preferred form ot structured do not Wish to limit myself to the precise form of structure sliovvn7 but desire to avail i myself of such variationsf'and modifications as come Within the scope of the appended claim.

Having thus described my invention What I claim as new and desire to secureaby Letters Patent is:

A device of the class described adapted for Y use with aA vehicle Wheel having a felly, bolts projected therethrough and a tire carried by said felly, comprising: .a plurality of sec- 'tions positioned on the tread portion of said l tire and extending circumferentially thereof;

oppositely disposed (3o-operating attachmentlipsswingably mounted on said sections, the

4clips on one 'side of said `fellybeing formed to lie in engagement With the side'face of said feily and provided With openings for accomodating the bolt-s projected through' through `the 'free `ends of said clips for f clamping the same in engagement with said felly.`

In testimonywvhereof, I have signed the foregoing.
